Abstract
A triboelectrically neutral polymer material which resists charging when contacted with another material is provided. The polymer material comprises at least a first polymer and a second polymer, the first polymer having a first rating on a triboelectric series and the second polymer having a second rating on a triboelectric series that is more negative than the first rating. A method of preparing the polymer material is also provided.

A polymer material comprising at least a first polymer or a first monomer of the first polymer and a second polymer or a second monomer of the second polymer, wherein the first polymer has a first rating on a triboelectric series and the second polymer has a second rating on a triboelectric series that is more negative than the first rating, and wherein the polymer material is triboelectrically neutral such that it resists charging when contacted with a material distinct from the polymer material.
A method of preparing a polymer material comprising the steps of mixing at least a first pre-determined amount of a first polymer or a first monomer of the first polymer and a second pre-determined amount of a second polymer a second monomer of the second polymer, the first polymer having a first rating on a triboelectric series and the second polymer having a second rating on a triboelectric series that is more negative than the first rating, wherein the first pre-determined amount and the second pre-determined amount are such that the polymer material resists charging when contacted with a material distinct from the polymer material.
A method of preparing a copolymer comprising the steps of co-polymerizing at least a first pre-determined amount of a first polymer and a second pre-determined amount of a second polymer, the first polymer having a first rating on a triboelectric series and the second polymer having a second rating on a triboelectric series that is more negative than the first rating, wherein the first pre-determined amount and the second pre-determined amount are such that the copolymer resists charging when contacted with a material.
